Paris shooting: Everything we know the morning after the deadly attack

A home in the suburbs of Paris has been searched by authorities after a gunman opened fire on police on the Champs-Elysees boulevard, killing one officer and wounding three people before being shot dead.

What exactly happened?

The attacker emerged from a car and used an automatic weapon to shoot at officers outside a Marks & Spencer store at the centre of the Champs-Elysees, anti-terrorism prosecutor Francois Molins said.

The gunman was shot dead by other officers, and a woman tourist was also wounded in the incident on Thursday night.

A terror investigation has been launched and authorities searched a home early on Friday in an eastern suburb of Paris believed to be linked to the shooting. A pump-action shotgun and knives were found in the gunman’s car.

A police document obtained by The Associated Press identifies the address searched in the town of Chelles as the family home of 39-year-old Karim Cheurfi, who has a criminal record.

Police have detained three of his family members for questioning, as investigators seek to determine whether he was acting alone and where he got his weapons.

The so-called Islamic State claimed responsibility just a few hours after the attack.

The extremist group gave a pseudonym for the gunman, Abu Yusuf al-Beljiki, indicating he was Belgian or had lived in Belgium, although Belgian authorities said they had no information about the suspect.

Two French officials said the gunman had been detained towards the end of February after speaking threateningly about the police, but he was then released due to a lack of evidence.

He was also convicted in 2003 of attempted murder in the shooting of two police officers.

Has it affected the French election?

The first round of the presidential election is to take place on Sunday and candidates have since cancelled or rescheduled their final campaign events ahead of it.

Conservative contender Francois Fillon, who has campaigned against “Islamic totalitarianism”, said he was cancelling his planned campaign stops on Friday.
